无法加载 DLL 'Microsoft.Quantum.Simulator.Runtime.dll' (CentOS 7)

Question

我正在尝试获取 Microsoft's Quantum Development Kit to work on a CentOS 7 machine. I followed the instructions 以安装 dotnet，而琐碎的 dotnet 'Hello World' 工作正常。我还从 yum 安装了 Visual Studio，并从 Visual Studio 资源管理器安装了 Microsoft Quantum Development Kit for Visual Studio。

克隆他们的 github 仓库后。我试试：

dotnet_vm: Teleportation$ cd ~/Quantum/Samples/Teleportation/
dotnet_vm: Teleportation$ scl enable rh-dotnet21 bash
dotnet_vm: Teleportation$ dotnet run
/home/user/Quantum/Microsoft.Quantum.Canon/Microsoft.Quantum.Canon.csproj : warning NU1603: Microsoft.Quantum.Canon depends on NETStandard.Library (>= 2.0.2-servicing-25519-03) but NETStandard.Library 2.0.2-servicing-25519-03 was not found. An approximate best match of NETStandard.Library 2.0.2 was resolved. [/home/user/Quantum/Samples/Teleportation/TeleportationSample.csproj]

Unhandled Exception: System.DllNotFoundException: Unable to load shared library 'Microsoft.Quantum.Simulator.Runtime.dll' or one of its dependencies. In order to help diagnose loading problems, consider setting the LD_DEBUG environment variable: libMicrosoft.Quantum.Simulator.Runtime.dll: cannot open shared object file: No such file or directory

   at Microsoft.Quantum.Examples.Teleportation.Program.Main(String[] args) in /home/user/Quantum/Samples/Teleportation/Program.cs:line 13

看起来是同样的错误。我尝试了我认为的 linux 等效解决方案：

cp ~/.nuget/packages/microsoft.quantum.development.kit/0.2.1809.701-preview/runtimes/linux-x64/native/Microsoft.Quantum.Simulator.Runtime.dll ~/.nuget/packages/microsoft.quantum.development.kit/0.2.1809.701-preview/lib/netstandard2.0/

我仍然遇到同样的错误。另外，我的计算机上没有启用 AVX 指令集（这可能是一个潜在问题？）。

例如

 grep flags /proc/cpuinfo 
flags       : fpu de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pse36 clflush mmx fxsr sse sse2 syscall nx lm nopl pni cx16 hypervisor lahf_lm abm
flags       : fpu de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pse36 clflush mmx fxsr sse sse2 syscall nx lm nopl pni cx16 hypervisor lahf_lm abm
dotnet_vm: Teleportation$

我没有任何 Windows 经验，这些看起来不像典型的 Linux 库（不是 .so 或 .a）。

问题：我如何让它工作？

Answer 1

Microsoft.Quantum.Simulator.Runtime.dll是一个普通的Linux库(.so)，只是为了更容易支持跨平台而重命名。

它看起来确实与的问题类似，但是您应该查看 Ubuntu 答案：使用 ldd 找出依赖项并安装缺少的任何东西。正如那个 post，问题很可能是你遗漏了 libgomp，但我不熟悉 CentOS。

不启用 AVX 会使速度变慢，尤其是在处理大量量子位时，但您仍然可以运行。

Answer 2

根据 El capi 的回答，我查看了链接到的库：例如

dotnet_vm: gcc-5.1.0$ ldd /home/user/.nuget/packages/microsoft.quantum.development.kit/0.2.1809.701-preview/lib/netstandard2.0/Microsoft.Quantum.Simulator.Runtime.dll

    linux-vdso.so.1 =>  (0x00007fff2f12b000)
    libstdc++.so.6 => /lib64/libstdc++.so.6 (0x00007f1fb5fee000)

    /lib64/ld-linux-x86-64.so.2 (0x00007f1fb656a000)

为了解决关于 GLIBCXX_3.4.21 的版本控制问题，我安装了 gcc-5.1.0（及其依赖项）。然后运行代码：

dotnet_vm: Teleportation$ dotnet run
